TO ALL WHOM IT MAY GONGERN:

Be it known that I, GEORGE W. JACKSON, of Wyalusing, Bradford eounty, in tbe State of Pennsylvania, have invented certain new and useful improvements in Platform Weighing-Scales; and I do hereby declare the following to be a. full and exact description of the same, reference being had to the drawings that accompany and form a part of these specifications, in which- Figure I, perspective view of tbe working parts beneath the upper framework,

Figure H, sectional view.

Figure IH, vien7 of some of tbe small parts forming clasp and bearings combined.

Letters A A', two square shafts, lying along each end, as shown; letters B B', levers leading to the scalebeam rod C; letters FF, the floor-timbers; letters e e e e, four links, on which the shafts A A are suspended; letters gg g g, fodr staples or stirrups, forming at the same time a bearing on the hooks e and bolts in connectim with the plates t'z'; letters h L 7L z, four staples on the opposite sides of the bars A, and in reverse position to g g g g; letters 1,' z', plates, one on the top ofV the other, at the bottom of the bars or shafts A A, and ay pair of these at each corner; letters m m 'm m, arms on the ends of the timbers F.

The object of my invention is to provide a more simple structure for platform scales, and the various parts so attached and combined as to be readily adjustable7 so that all the bearings-may be kept in desired position.

The bolts or staples y and L are made of steel, and are easily taken out Without removing any other parts and may be sharpened and polished readily and replaced, or duplicates formed and put in; although in doing this, both gand i should'not be removed at the same time. After one has been removed and repaired and replaced, the other can be, without dsarranging the parts.

What I cla-im, and desire to secure by Letters Patent, is-

1. The use ofthe stirrups g and the stirrups L, when performing the double purpose of affording bearings for the Boor-beams Ic k and the hooks or links e, and of elasping the shafts A, in connection with the plates t', all arranged substantially as described, and for the purposes set fort-h.

2. I cla-im tbe slotted arms m on the ends of the Hoor-timbers F, when used in platform weighing-scales, substantially as shown and described.

GEORGE W. JACKSON.
